PAINT.

SPECIFICATION forming part of Letters Patent No. 786,023, dated March28, 1905.

Application filed June 21, 1904. Serial No. 213,554.

To all whom it may concern.-

Be it known that I, GEORGE W. GEsNER, a citizen of the United States,residing in the borough of Manhattan, in the city and State of New York,have invented a new and useful Improvement in Paints or Pigments, ofwhich the following is a specification.

My invention relates to the manufacture of a paint or pigment composedof an alloy of hydrogen and iron, finely comminuted, the hydrogen beingpresent in the alloy in such quantity as to prevent the action of alloxidizing agents, and linseed or other oil or vehicle, suitable to givethe proper consistence for use. A drier is added when desired.

In using linseed-oil the proportions are about one gallon of mixed rawand boiled linseedoil to thirty-three pounds of the alloy in a powderedstate.

The paint can be applied in the manner of any paint. It flows freely andcovers well and possesses great power of resisting corrosive influences.It will be of special value for the preservation of structural iron,sheet-iron for roofing, ships bottoms, bridges, &c.

The manufacture of the alloy is generally set forth in Letters Patent tome, No. 604,580,

dated May 2 1, 1898; No. 642,320, dated January 30, 1900; No. 646,552,dated April 3, 1900; N 0. 647,960, dated April 24, 1900; N0.649,049,dated May 8, 1900; No. 651.033, dated June 5, 1900; No. 670,775, datedMarch 26, 1901. These Letters Patent disclose in detail the alloy andprocesses and apparatus ,for making the same.

It will suffice in the present case to state that the alloy of iron andhydrogen is produced from iron, ore, steel, manufactured scrap or anyother iron, and hydrogen. The association or combination of the hydrogenis stable under all conditions of heat. It resists oxidation that mightbe induced through any cause.

The alloy is produced by exposing the iron in a converter at atemperature of about 1,800 Fahrenheit to an atmosphere of hyrogengenerated by steam injected into the converter from a steam-boilerthrough a coil of iron pipe constituting the hydrogen-generator andheated either in a separate furnace or in the furnace in which the alloyis made. Another mode of producing the alloy is to expose scrap-iron tohydrogen in the converter and remove the scale formed upon it bystirringbars inserted through the converter side. Another mode is toforce the hydrogen through molten iron. Any of these modes can befollowed by a further process of grinding and screening, the resultingiron alloy being thus reduced to a fine powder. This powder produced bythe grinding and screening of the alloy, made by whichever mode, is theform of the alloy used in the manufacture of the paint. The powder thusproduced is either reground with the linseed or other oil or vehicle orsimply mixed with it.

I do not show any special apparatus for the grinding together or mixingthe powdered alloy and the oil or other vehicle, as any ordinarypaint-mill or any vessel for mixing is suitable for that purpose.

The alloy can be pounded in a mortar or crushed by stamps as well asground before being screened.

I claim as my invention 1. The paint described, composed of a liquidvehicle with a drier, and an alloy of hydrogen and iron in a pulverizedstate, the hydrogen being in such proportion as to prevent oxidation orcorrosion in the said alloy.

2. A paint composed of a pulverized alloy of hydrogen and iron, thehydrogen. being present in such proportion as to prevent oxidation orcorrosion in the said alloy, and linseed-oil.

3. A paint composed of a pulverized alloy of iron and hydrogen, thehydrogen being present in the alloy in the proportion of about elevenone-hundredths of one per cent. and upward, a vehicle and a drier.

In testimony that I claim the invention above set forth I afiix mysignature in presence of two witnesses.
